-CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 739,706, dated September 22, 1903. Application filed August 8, 1898- Serial No. 688,019- (No model.)

To all whom it may concern.-

Be it known that I, FRED J. NUTTING, acitizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash-Registers, of which I declare the following to be a full, clear, and exact description. This invention relates to improvements in cash-registers, and has more particular relation to improvements in operating devices for the same, and especially for registers of the type patented to H. Oook, No. 464,294, dated December 1, 1891.

The primary object of the invention is to provide means for operating a register by utilizing the weight of the operator as the propelling force.

In the appended drawings, forming part of this specification, Figure 1 represents a side elevation, partly in section and partly broken away, of the devices embodying my invention applied to a register ofsubstantially the same construction as that mentioned above. Fig. 2 represents a vertical transverse section through the upper portion of my improved operating attachment. Fig. 3 represents a top plan view, partly broken away, of the op erating-platform; and Fig.4 represents an enlarged detail side elevation of a modified form of connection between the platform and the operating devices.

In the said drawings, 1 represents the frame of the cash-register, to which I have shown my invention applied; 2, the power-shaft of the same; 3, the operating-platform; 4, the

operating rack-bar, and 5 the release-lever.

The register proper shown in the present instance is of substantially the same construction and operation as that described in the aforesaid patent, and attention is therefore called to the latter for a detail description of the parts. The power or revolution shaft 2 of this machine is provided at one end with a gear-wheel 6 and a latch-disk 7, the latter be:

ing provided with a peripheral notch or recess 8, into which the end of a locking-pawl 9 is normally drawn by the action of a coilspring 10. The forward end of said pawl 9 is formed with a notch 11, the upper wall of which is inclined, so that said pawl is oper ated to release the disk when a projection 12, mounted on the lever 5, is forced against it by the operation of said lever, the lower wall of said notch contacting with the said 'pro- 5-5 jection and preventing overthrow of said pawl. Motion is transmitted to the said gear 6 by a gear-wheel 13, which in turn receives motion from a gear-wheel 14, loose upon a shaft 15, journaled in the frame of the ma- 6o chine. This shaft is also provided with a pinion 16, fast thereon and meshing with the up per portion of the vertical rack 4, so as to receive motion therefrom. Further, said'shaft is provided with a stop-disk 17, fast thereon and formed with a stop-shoulder 18, which latter is arranged to be engaged by a pivoted stop-lever 19. This lever is formed with a looking-shoulder 20 and is normally held against the disk 17 by a coil-spring 21, so that said shoulder will engage the shoulder 18, and thus lock the said disk. The locking-lever 19 is arranged to be moved away from the disk 17 to disengage the shoulders and free said disk by a push-bar 22, mounted in suitable guides and connected to the lever 5 by a pivoted link 23. The said locking-disk 17 is provided with a pivoted pawl 24, which engages'a ratchet-wheel 25, fast to the gearwheel 14, whereby the movement of the disk 8o 17 in one direction will rotate the wheel 14; but a reverse movement will simply result in the pawl riding over the teeth of the ratchet-wheel. The aforesaid rack-bar 4 receives its motion from the pivoted incline platform 3, to which its lower end is pivoted, and it is held into positive mesh with the wheel 16 at all timesby an antifriction-wheel 26, which engages its rear side. The free end of the platform 3 is normally held in an 0 elevated position by a coil-spring 27, secured to said platform, and also to a bracketor yoke 28, which extends over said platform, this upward movement of the platform being limited by an adjustable stop-screw 28 5 on the platform and which isarranged to abut against a rigid bracket 29. An approximately triangular-shaped plate 30 is rigidly secured to the lower end of the rack-bar 4 and is provided at one of its lower corners with a pendent piston-rod 31, carryinga piston 31 at its lower end. This piston is ar ranged to operate in a valved cylinder 32,

which. is supported by two pivoted rods 33,

pivoted to opposite sides'of the same, so that it may tip from side to side to accommodate itself to the changing positions of the bar 4 and rod 31. In the modified form of connection shown in Fig. 4 the lower end of the rack-bar simply rests upon the platform and is held normally in such contact by a coilspring 34, connected to said platform, and an eye formed in said bar. This peculiar structure relieves the bar of excessive shock or tion releases the mechanism which has been locked by the lever 19 and allows the rackbar to descend without jar, its movement being cushioned by the air cylinder and piston. The descent of said rack-bar operates the gearing, as before described, and thus rotates the power-shaft 2 one complete revolution. When the operator steps from the platform, the spring 27 draws the same upward to raise the bar 4:, the valves in the bottom of the cylinder 32 opening during such operation to allow free movement of the piston. The upward movement of the rack-bar causes a backward rotation of the shaft 15; but this motion is not transmitted to the gear 14, as the pawl 24 rides over the ratchet-wheel 25 when the movement is in this direction. By the peculiar structure of the latch-lever l9 and the disk 17 the weight of the operator is not thrown upon the Working parts of the register when the operator steps upon the platform, but upon the said latch-lever. Any suitable casing is arranged about the gearing, rack-bar, latch, &c., for protecting the same, a suitable slot being formed in said,

casing for the passage of said rack-bar. I do not care to limit the application of my invention to machines of the type shown in the drawings, as the same may be equally well applied to other classes of machines.

Having thus described myinvention, what Iclaim as new,'and desire to secure by Letters Patent, is-

1. The combination with registerractuating devices of a platform for operatingv said devices, a rack-bar connected to said platform,
